| Abstract: | Low mole ratio(F:U)recipe was applied to prepare low toxic UF resin,and appropriate quanti-ties of polyvinyl alcohol, phenol were added in preparing process. The results showed the free formaldehyde content in the prepared resin was steadily lower than 0.15%, and water resistant property of the resin was improved. |
